【Market Flash】Alexander Blok, an Israeli-Russian national, was extradited to the United States on October 29 to stand trial. U.S. prosecutors allege that in August 2022, he exploited a vulnerability in the Nomad cross-chain bridge, personally withdrawing approximately $2.8 million in tokens. This exposed the vulnerability and prompted others to follow suit, withdrawing more than $186 million. He was arrested at Israel’s Ben Gurion Airport in May 2025, and his extradition was completed after Israel’s Supreme Court rejected his appeal.

What lessons do you think this prosecution over an old case offers for cross-chain bridge security?
